Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1975778 is determined by strict equivalence across the following critical parameters:

• Connector Architecture: 10-position configuration with 0.300" (7.62mm) pitch spacing
• Electrical Performance: 41A current capacity (IEC/UL), 1 kV (IEC) / 600 V (UL) voltage ratings
• Mechanical Interface: 180° free-hanging in-line orientation with screw-rising cage clamp termination
• Wire Compatibility: Support for 8-24 AWG (0.2-10mm²) conductor gauges
• Material & Safety: Polyamide housing with UL94 V-0 flammability rating and tin contact finish

The Phoenix Contact 1977914 meets all substitution criteria as an active-status equivalent within the COMBICON PC series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1777914 is the direct active-status equivalent for the obsolete 1975778 model. Both components share identical electrical ratings, mechanical interfaces, and material specifications within the COMBICON PC series. The 1777914 is currently in active production status with full inventory availability.

The 1777914 incorporates retention latches on the non-wire side, providing enhanced mechanical stability during mating operations. The insulation height differential (0.776" versus 0.902") and broader torque specification range (0.5-0.8 Nm versus 0.7-0.8 Nm) represent design refinements that maintain full backward compatibility while improving assembly flexibility.

Both components maintain identical RoHS compliance status and carry equivalent electrical certifications (IEC and UL). The 1777914 carries ROHS3 compliance designation, reflecting current regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1777914 directly replace the 1975778 in existing installations?

A: Yes. Both components share identical electrical ratings (41A at 1 kV IEC), mechanical pitch (0.300" / 7.62mm), termination method (screw-rising cage clamp), and wire gauge compatibility (8-24 AWG). The 1777914 is the active-production equivalent.

Q: What is the significance of the insulation height difference between these parts?

A: The 1777914 features a lower insulation height (0.776" versus 0.902"). This represents a design optimization that does not affect electrical or mechanical performance. Both dimensions are within the COMBICON PC series specifications and maintain full compatibility with mating connectors.

Q: Does the addition of retention latches on the 1777914 affect compatibility?

A: No. The retention latches on the non-wire side of the 1777914 are a supplementary feature that enhances mechanical stability during mating. They do not alter the electrical interface or wire termination characteristics and are fully compatible with standard COMBICON PC receptacles.

Q: Are there packaging differences between these components?

A: The 1975778 was supplied in standard packaging, while the 1777914 is available in bulk packaging. Both are new original stock. Packaging format does not affect component performance or compatibility.

Q: What is the difference between the torque specifications?

A: The 1975778 specifies a fixed torque range of 0.7-0.8 Nm, while the 1777914 allows 0.5-0.8 Nm. The broader range on the 1777914 provides greater assembly flexibility while maintaining the upper torque limit of the original specification. Both ranges ensure proper screw-rising cage clamp engagement.

Q: Are both components RoHS compliant?

A: Yes. The 1975778 carries RoHS compliance certification, and the 1777914 carries ROHS3 compliance, reflecting current regulatory standards. Both meet environmental compliance requirements for electronic components.
